Ocean Rig UDW Inc., a global provider of offshore deepwater drilling services, today announced that on May 15, 2012, its Ocean Rig Corcovado drillship completed the general testing of equipment as required by Brazil’s oil giant Petrobras.
The drillship has now commenced revenue-generating drilling operations in Brazil. The Ocean Rig Corcovado will stay with Petrobras for three years on a contract worth approximately $650 million.
This is the second Ocean Rig’s drillship under a contract with Brazil’s state controlled Petrobras. The company’s Ocean Rig Mykonos drillship had started drilling offshore Brazil in March this year under a similar contract.
Ocean Rig’s drillships are based upon the Saipem 10K design, and built by a proven shipyard, Samsung Heavy Industries. They are a successful and well proven design complete with full dual derrick enhancements to ensure optimal operational efficiency.
The company owns and operates 9 offshore ultra deepwater drilling units, comprising of 2 ultra deepwater semisubmersible drilling rigs and 7 ultra deepwater drillships, 3 of which remain to be delivered to the company during 2013.

Mzia-1 is BG Group’s first discovery within the deeper Cretaceous section and opens an extensive new play fairway within the Group’s offshore acreage in Blocks 1, 3 and 4, to complement the now proven Tertiary fairway.
Preliminary evaluation of the results indicates 55 metres of natural gas pay in good quality sands. An extensive logging programme has been completed, including the acquisition of pressure data and gas samples.
Significantly, the well has de-risked a number of adjacent Cretaceous prospects, which could form part of a future Mzia hub. These prospects are expected to be tested in a future appraisal programme to be defined following incorporation of data from this new well and 3D seismic.
The new resources proven by Mzia and the potential of adjacent prospects are currently under evaluation. Prior to drilling Mzia-1, BG Group had estimated mean total gross recoverable resources approaching 7 trillion cubic feet of gas from the four previous discoveries drilled in Tanzania.
Mzia-1 is approximately 45 kilometres offshore southern Tanzania in a water depth of 1 639 metres. It is some 23 kilometres from the Jodari-1 discovery and is part of the 2012 three-to-four well exploration programme.
Following the imminent completion of operations at Mzia, the Deepsea Metro-1 will relocate to Block 3 for the drilling of the next exploration prospect, Papa-1.
BG Group as operator has a 60% interest in Blocks 1, 3 and 4 offshore Tanzania, with Ophir Energy plc holding 40%.
